Using the sauté function, sauté andouille sausage in bacon fat (or other neutral tasting oil) until brown. This may take between 3-5 minutes.
Once sausage is browned remove from instant pot with a slotted spoon, reserving any oil that is remaining. Add additional oil or bacon fat it needed.
With the sauté function, sauté celery, onions, and bell pepper for 3-5 minutes or until softened.
Add in garlic and stir, allowing to only sauté for about a minute.
Add sausage back into the instant pot along with the remaining ingredients.
Stir to combine then add the lid and close the seal.
Set the instant pot to pressure cook on high for 30 minutes.
After 30 minutes, open the valve to allow a quick release.
You can either serve as is or turn the instant pot back to saute to allow the sauce to thicken over the high heat. I also like to take a potato masher and mash up some of the beans and allow some to stay whole.
Serve over white rice. Here’s my perfect white rice recipe.
